Cl. 68-22 2 Claims ABSTRACT OF THE DISCLOSURE Apparatus for continuously rinsing cloth comprising a rinsing chamber having cloth guiding means and sets of eccentrically mounted rollers and cooperating walls on either side of the cloth path by which the cloth is beaten and forcibly rinsed. Cooperating sprays, squeeze rolls and final bath means are also provided.

BACKGROUND OF THE INVENTION Field of the invention The invention relates to textile treating machinery, more particularly to apparatus for continuously rinsing cloth.

Description of prior art Known apparatus for rinsing cloth is not as advantageous as is desirable.

SUMMARY OF THE INVENTION SHORT DESCRIPTION OF THE DRAWINGS In the drawings: FIG. 1 is a side elevational view, in longitudinal section of a cloth rinsing apparatus according to the invention; FIG. 2 is a front view of the apparatus shown in FIG.

FIG. 3 is the same with FIG. 1 except that another form of cloth vibrating roller system is employed.

DESCRIPTION OF PREFERRED EMBODIMENT Referring to the drawings, particularly FIGS. 1 and 2 thereof, a cloth rinsing apparatus according to the inven tion comprises a rinsing bath 1 and a pair of squeeze rollers 3 positioned in the upper part of the rinsing bath 1.

Partition walls 4 and 5 are provided for defining an eccentric roller chamber 6 therebetween. The partition walls 4 and 5 are formed of a respective plurality of vertically interconnected arcuate plates 4' and 5', the respective sets of arcuate plates being opposed to each other.

Eccentric rollers 8 and 9 are positioned in the arcuate spaces 4" and 5" of the arcuate plates 4 and 5', respectively. It is seen from FIG. 1 that the two cooperating opposed eccentric rollers 8 and 9 of each pair have the same phase of rotation, whereas the phases of rotation of vertically adjacent eccentric rollers 8 are opposite to each other, the same being true also of vertically adjacent eccentric rollers 9.

There is a small clearance between the cooperating 0pposed eccentric rollers 8 and 9 of each pair and cloth to be rinsed shown at 7 is passed through such clearances.

In this embodiment shown in FIGS. 1 and 2, there are six eccentric rollers 8 on the side of one partition wall Patented Sept. 9, 1969 "ice 4 within the eccentric roller chamber and six eccentric rollers 9 on the side of the other partition wall 5.

Fresh water supply tubes 12 and 13 are positioned below the contact region of the squeeze rollers 3. Further, lateral plates 19 are positioned on both sides above the contact region of the squeeze rollers 3 so as to define a fresh water reservoir 20. The front end of a water supply tube 14 is placed in said fresh water reservoir 20 so as to constantly supply the latter with fresh Water.

An overflow tube 15 is provided for keeping constant the level 1 within the rinsing bath 1.

The cloth 7 to be rinsed is passed around a guide roller 16, vertically downwardly guided from the top of the rinsing bath 1 to the bottom of the rinsing bath 1, where it is passed around guide rollers 17 and 18 and guided upwardly to pass through the eccentric roller chamber 6, where it is pressed from right and left by the eccentric rollers 8 and 9 so that it travels upwardly while vibrations are imparted thereto as it is bent in a Wave form, and finally it is passed between squeeze rollers 3 and upwardly taken out. Thus, by being passed between the vertical arrays of the eccentric rollers 8 and 9 on its way from the guide roller 18 to the squeeze rollers 3 in this manner, the cloth 7 is subjected to forced vibrations by the eccentric rotation of the eccentric rollers 8 and 9 positioned on both sides and also to vibrations due to revolving water current pressure within the arcuate spaces 4" and 5" produced by the eccentric rotation of the eccentric rollers 8 and 9, whereby the cloth is rinsed. Since the cloth 7 is subjected to such actions alternately by the several sets of cooperating opposed eccentric rollers 8 and 9 as it travels upwardly, the cloth is subjected to repeated bending and beating so that the dust, dirt and other undesirable materials depositing on and existing in the texture of the cloth are effectively removed.

After the cloth thus rinsed as it is passed through the eccentric roller chamber 6, and immediately before it is passed to the nip between the squeeze rollers 3, both surface of the cloth are rinsed with fresh water jetting from the fresh water supply tube 12 and 13. The fresh water supply tubes 12 and 13 are provided with jet orifices 12' and 13, respectively, through which fresh water is jetted against both surfaces of the cloth to effect final finish rinsing.

The cloth thus rinsed for finish with fresh water is passed between the squeeze rollers 3 whereby it is dehydrated. It is then passed through the fresh water reservoir 20 above the contact region of the squeeze rollers 3, so that it absorbs fresh water and is then upwardly con veyed either to enter the next rinsing bath or to be squeezed and dehydrated by squeeze and dehydrating rollers.

Referring to FIG. 3, there is shown another embodiment of the invention, wherein the eccentric rollers shown in the preceding embodiment are replaced by wing-like rollers 8 and 9. Each wing-like roller has an oval sectional shape with a narrowed central region, having a shaft a extending through the center thereof. The cooperating opposed wing-like roller 8 and 9 of each pair are in mutually orthogonal phase and vertically adjacent wing-like rollers 8 and also vertically adjacent rollers 9 are in mutually orthogonal phase, respectively. There is a small clearance between the cooperating opposed wing-like rollers 8 and 9 of each pair and cloth 7 to be rinsed is passed through such clearances. In thi embodiment shown in FIG. 3, six wing-like rollers 8 are provided on the side of one partition wall 4 within the wing-like roller chamber 6 and six wing-like rollers 9 are provided on the side of the other partition wall 5.

It is seen from the foregoing that according to the invention there is provided a cloth rinsing apparatu comprising a rinsing bath 1, partition walls 4 and 5 having a number of arcuate spaces 4" and 5" respectively to define an eccentric or wing-like roller chamber 6, eccentric or wing-like rollers 8 and 9 positioned in said arcuate space 4" and 5", respectively, whereby cloth 7 to be rinsed is subjected to beating by the rotation of said rollers 8 and 9 and also to forced rinsing by revolving water currents within the arcuate spaces 4" and 5" produced by the rotation of the rollers 8 and 9. As a result of this arrangement, the rinsing action on the cloth is satisfactory and is continuously effected with improved rinsing efficiency. Further, in this invention, since the cloth is passed through the fresh Water reservoir formed in the recessed region of the upper part between the top squeeze rollers 3 thereby to replace the contaminated water in the rinsing bath by fresh water, the rinsing of cloth is more nearly perfectly effected.

What is claimed is:

1. A cloth rinsing apparatus comprising two partition walls positioned in a rinsing bath each having a number of arcuate spaces to define an eccentric roller chamber, eccentric rollers each in the respective arcuate spaces, whereby cloth to be rinsed passing upwardly through the eccentric roller chamber is subjected to heating from both sides by the eccentric rollers and also to forced rinsing by revolving water currents within the arcuate spaces produced by the rotation of the eccentric rollers, said cloth being finally passed between a pair of squeeze rollers positioned on the top to remove the water from the cloth and being then allowed to absorb fresh water contained in a fresh Water reservoir formed in the recessed region above the contact between said squeeze rollers.

2. A cloth rinsing apparatus comprising two partition walls positioned in a rinsing bath each having a number of arcuate spaces to define a Wing-like roller chamber, wing-like rollers each in the respective arcuate spaces, whereby cloth to be rinsed passing through the winglike roller chamber is subjected to alternate beating from both sides by the wing-like rollers and also to forced rinsing by the revolving water currents within the arcuate spaces produced by the rotation of the winglike rollers, said cloth being finally passed between a pair of squeeze rollers to remove the water from the cloth.
